DISCUSSION
ISSUED AT 1045 PM EST TUE NOV 4 2025
NOT MUCH HAS CHANGED ACROSS THE FLORIDA KEYS THIS EVENING. HIGH
PRESSURE ALONG THE SOUTHEAST US COASTLINE CONTINUES TO PROMOTE
MODERATE TO FRESH NORTHEAST TO EAST BREEZES. A CLOUD SHIELD
ORIGINATING FROM THE NORTHWESTERN CARIBBEAN SEA STREAMS OVER OUR
AREA MAKING FOR BROKEN TO OVERCAST SKIES. WHILE KBYX RADAR HAS
DETECTED SOME STRATIFORM RAINFALL, VERY LITTLE PRECIPITATION HAS
BEEN OBSERVED OVER THE ISLAND CHAIN. TEMPERATURES ARE STILL NEAR
NORMAL FOR THIS TIME OF YEAR RANGING IN THE MID 70S WITH ONLY A
SLIGHT DRYING IN THE DEWPOINTS NOW IN THE MID TO UPPER 60S.
THE SURFACE HIGH IS PROGGED TO DRIFT OUT INTO THE WESTERN NORTH
ATLANTIC IN THE SHORT TERM. THIS WILL ALLOW WINDS TO SLACKEN
GRADUALLY OVERNIGHT AND INTO TOMORROW. THIS EVENING'S KKEY 00Z
SOUNDING SHOWS A VERY MOIST PROFILE CONSIDERING THE RECENT FRONTAL
PASSAGE, BUT ESSENTIALLY NO INSTABILITY BOTH LIKELY DUE TO THE
COPIOUS CLOUD COVER THROUGHOUT TODAY. REDUCED SURFACE CONVERGENCE
FROM SLOWING WINDS AND NO INSTABILITY WILL SUPPORT NEAR NIL POPS
FOR THE REST OF TONIGHT AND INTO TOMORROW. HIGH PRESSURE WILL THEN
BUILD BACK OVER EASTERN CONUS SUPPORTING NORTHEAST TO EAST BREEZES
AND SEASONAL CONDITIONS GOING INTO THE MIDWEEK.
MARINE
ISSUED AT 1045 PM EST TUE NOV 4 2025
A SMALL CRAFT ADVISORY REMAINS IN EFFECT FOR THE STRAITS OF
FLORIDA. SMALL CRAFT SHOULD EXERCISE CAUTION IN THE GULF WATERS
AND HAWK CHANNEL. FROM SYNOPSIS, STRONG SURFACE HIGH PRESSURE
WILL SLOWLY MIGRATE EASTWARD ACROSS THE SOUTHEAST U.S. AND
MAINTAIN MODERATE TO FRESH BREEZES THROUGH EARLY WEDNESDAY.
THEREAFTER, BREEZES SLACKEN AS THE RIDGE MOVES OUT INTO THE
ATLANTIC AND WEAKENS.
AVIATION
(00Z TAFS)
ISSUED AT 1045 PM EST TUE NOV 4 2025
VFR CONDITIONS WILL PREVAIL AT BOTH EYW AND MTH TONIGHT AND INTO
TOMORROW. NEAR SURFACE WINDS WILL BE GENTLE TO MODERATE OUT OF
THE NORTHEAST, BECOMING NORTHEAST TO EAST AND GRADUALLY SLACKENING
INTO TOMORROW.
